The QT2 transistor characteristic plotter can measure the low-frequency DC parameters of diodes and transistors, with a maximum collector current exceeding 50A, and can meet the testing of devices below 500VA.
The QT2 Transistor Characteristic Display Instrument, represented by Shanghai Yice Electronics, provides low‑frequency DC parameter measurement for diodes and transistors. It supports high‑current testing up to 50 A and includes a high‑voltage module for breakdown voltage and reverse leakage tests up to 5 kV. Key features include multiple voltage and current ranges, a test current sensitivity down to 0.5 µA/div, and a display area of 10 × 10 div. The unit operates from AC 220 V/50 Hz, has an apparent power of about 80 VA (up to 300 VA max), and measures 300 mm × 408 mm × 520 mm, weighing over 30 kg. This manual is written in Chinese.
